drm/i915/lnl: Add CDCLK table

Add a new CDCLK table for Lunar Lake.

v2:
  - Remove mdclk from the table as it's not needed (Matt Roper)
  - Update waveform values to the latest from spec (Matt Roper)
  - Rename functions and calculation to match by pixel rate (Lucas)
v3: Keep only the table: as far as intel_pixel_rate_to_cdclk()
    is concerned, the minimum cdclk should still be half the pixel
    rate on Xe2 (bspec 68858:
    "Pipe maximum pixel rate = 2 * CDCLK frequency * Pipe Ratio")
    (Matt Roper)

Bspec: 68861, 68858
